Let's divide 13868057 by 491
The aim is to understand the frequency of 491 in 13868057.

Step 1:
When dividing 1 by 491, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 491

Let's proceed to step 2:
When dividing 13 by 491, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 491

Advancing to step 3:
491 can be fit into 138 0 times, resulting in a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 138 to get 138.
Take the next digit (6) from the dividend and append it to 138, then repeat: 1386 / 491

Let's proceed to step 4:
If we divide 1386 by 491, we get 2 and a remainder of 404.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 404 after subtracting 982 from 1386.
Fetch the next digit (8) from the dividend, attach it to 404 and continue: 4048 / 491

Step 5:
When dividing 4048 by 491, we get 8 with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 3928 away from 4048, we end up with 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 491

Let's proceed to step 6:
491 goes into 1200 2 times with a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
If we take 982 away from 1200, we end up with 218.
Append the next digit (5) from the dividend to 218 and continue with: 2185 / 491

Step 7:
The number 491 fits into 2185 4 times, leaving a remainder of 221.
The number 4 becomes the next digit in our result. 
Result so far: 2824.0
If we take 1964 away from 2185, we end up with 221.
Fetch the next digit (7) from the dividend, attach it to 221 and continue: 2217 / 491

Advancing to step 8:
491 goes into 2217 4 times with a remainder of 253.
Write down 4 as next digit of the result. 
Result so far: 28244.0
The remainder is 253 after subtracting 1964 from 2217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
491 goes into 2530 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 28244.5
The remainder is 75 after subtracting 2455 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
750 divided by 491 is 1 with a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 28244.51
If we take 491 away from 750, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 11:
491 can be fit into 2590 5 times, resulting in a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 28244.515
Subtract 2455 from 2590 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 12:
When dividing 1350 by 491, we get 2 with a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 28244.5152
Subtract 982 from 1350 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 13:
3680 divided by 491 is 7 with a remainder of 243.
Record the quotient 7 as the next digit in the result. 
Result so far: 28244.51527
Subtract 3437 from 3680 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 14:
491 can be fit into 2430 4 times, resulting in a remainder of 466.
Put 4 as the next digit of the answer. 
Result so far: 28244.515274
If we subtract 1964 from 2430, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 15:
If we divide 4660 by 491, we get 9 and a remainder of 241.
Record the quotient 9 as the next digit in the result. 
Result so far: 28244.5152749
Subtracting 4419 from 4660 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 16:
The number 491 fits into 2410 4 times, leaving a remainder of 446.
Use 4 as the next digit of our solution. 
Result so far: 28244.51527494
Subtract 1964 from 2410 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

After the division, we end up with 28244.51527494 and a remainder of 4.46e-07.
